Bus interface for car audio
BA8272F
The BA8272F is a bus interface IC (slave side) developed for car audio applications. When used with the BA8272F (mas-
ter side), it is possible to construct a communication system for the deck and components such as power amplifiers, CD
and MD changers, tuners and TVs using BUS ON, DATA, CLOCK and RESET signals.

Operation notes
(1)
We guarantee the application circuit design, but
recommend that you thoroughly check its characteristics
in actual use. If you change any of the external compo-
nent values, check both the static and transient charac-
teristics of the circuit, and allow sufficient margin in your
selections to take into account variations in the compo-
nents and ICs.
Note that Rohm has not fully investigated patent rights
regarding this product.

Based on the EIAJ static electric destruction volt-
age measurement (C = 200pF and R = 0
), the with-
standing voltage of pins 4, 5 and 12 has been determined
to be 200V or less. Take due care.
